A practical method of selective alkylation of the third hydroxyl group of disubstituted tert-butyl-calix[4]arenes using anhydrous barium hydroxide as a base was developed in this study. The use of this method in the synthesis of inherently chiral der

A preparative method for the synthesis of optically pure N-(1-phenylethyl)amides of inherently chiral (cR)- and (cS)-dibenzoyloxy-calix[4]arene acetic acids has been developed. Their absolute stereochemical configuration was determined by X-ray diffr

Abstract: This review summarized and systematized the currently known methods of substituting phenolic fragments of calix[4]arenes in the para-position, mainly focusing on the conditions of regioselective carrying out such processes. The reactions of

Inherently chiral dialkyloxy-calix[4]arene acetic acids with asymmetric placement of substituents on the lower rim of the macrocycle were first studied as enantiodiscriminating additives to the mobile phase MeCN/H2 O/HCOOH (75/25/0.02 by volume) in t

The enantiodiscrimination properties of stereomerically pure inherently chiral calix[4]arene acetic acids, as well as their esters and amides in relation to 1-phenylethylamine stereoisomers in liquid and gaseous phases were studied by means of proton
